What was exposed
The register’s list does not say what was exposed; the notice it links to (under Sources) usually does.
Before the notice: the ransomware gang RansomHub named Tekni-Plex on its leak site on 13 December 2024, 285 days before this was reported. Matched by the organisation’s name: the notice itself does not say who the attacker was.
Look for Tekni-Plex, Inc.’s own notice or letter: it should say what of yours was involved. Keep it.
